XSLT encoding ??

[resolutionsnet]

Hi,

I raised as message earlier in this forum with regards to an error when
preforming a XSLT transform (see bottom of this message).

On further investigation I'm find that some of the XSLT file have an
namespace for encoding i.e.
<xsl:stylesheet xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
xmlns:e="http://xxx.co.uk/xxx" xmlns:msxsl='urn:schemas-microsoft-com:xslt'
xmlns:var='urn:var' xmlns:userJScript='urn:userJScript'
exclude-result-prefixes='msxsl var userJScript DateHelper e'
xmlns:DateHelper="urn:extn-obj" version='1.0'>

and the elements are being referenced as such e.g.
<xsl:if test='e:street'><Address1><xsl:value-of
select='e:street/text()'/></Address1></xsl:if>

Could this somehow have an affect on the below message

============
Whilst performing a simple XLST transform, I am receiving a
CryptographicException. No encryption is being used by the program itself.
At present I have found no pattern into reproducing the error, seemingly
random but often.

The stack trace is as follows;

System.Security.Cryptography.CryptographicExceptio n : The parameter is
incorrect.

Could anyone point out any possible areas where I could investigate, i.e.
Would SSL have an affect, would the XSLT encoding uft-8 instead of uft-16 be
an issue
